NTT DoCoMo will sell the iPhone 5s and 5c with a SIM lock.
Since 2010, DOCOMO has been pledging to allow the SIM unlock across all its smartphone range, which it started doing. Was it hoping that the others carriers would follow suit (they didn’t), that the ministry of telecommunications would enforce it (it didn’t)? Or was it just an attempt to undercut the competition all the while waiting for the iPhone?
In any case, DOCOMO will not SIM unlock the iPhone .
